nanoKeyer

I’m pleased to report that Oscar, DJ0MY, has created an open source hardware initiative and kit offering called nanoKeyer. This project utilizes my Arduino keyer code and the Arduino Nano, a smaller cousin of the Arduino Uno, but fully software compatible.

Oscar is offering the kit at a reasonable price, but also provides Gerber files on his site for those wishing to reproduce the hardware design. The hardware kit features three memory buttons, a speed potentiometer, a PS2 Keyboard connector, and optically-isolated keying and PTT lines. The Arduino Nano module that mates with the nanoKeyer supports the K3NG keyer code command line interface and K1EL Winkey emulation via the built-in USB port. The Arduino Nano is programmed via a typical Windows, Mac, or Linux machine with free software.

This kit offers commercial / contest quality performance and features in an open source package that can easily be assembled by beginners or customized by advanced experimenters.
